I realise I'm going to get beaten to death for this but I have one of those "beasts" and they are bad boys. 105 mph, no way stock, maybe with some bucks stuck in there. I ride with about 15 other guys with Zillas in different stages of "tweaked", they run like nothing I have seen to date, minus major upgrades, big bucks and much inconvienience, on other quads. It's a 2 stroke 500, it should scream. As with any other situation, "eat anything for breakfast" would depend on the rider, somewhat. Bone stock vs. Bone stock anything then or now, zilla, but it should. Technology is closing the gap quick, thats where skills come in. This should make for some interesting conversation...
